1) Moon: B — you are given the central mass and orbital radius, so use v = sqrt(G M / r).
2) Satellite: A — you are given the orbital period, so use v = 2π r / T (with r = R_earth + 150 km and T = 90 min).
2) Satellite: A — you are given the orbital period, so use v = 2π r / T (with r = R_earth + 150 km and T = 90 min).
